Astrology: your zodiac sign, rising sign, and birth chart

Astrology is a symbolic system that associates meanings with the positions of the celestial bodies. It starts from a verifiable fact: the place in the zodiac where the Sun, the Moon, and each planet stand, recorded for a precise date, time, and place. It then applies a language inherited from tradition: signs, houses, aspects. The result, the birth chart, reads like a portrait to be interpreted. It does not describe a future written in advance and does not replace any professional advice.

No. Astronomy, which calculates the position of the celestial bodies, is a science; astrology, which gives them a meaning, has received no scientific validation, and the studies that looked for a link between signs and character found no solid one. Versana presents it as a cultural tradition and a tool for personal reflection. The site’s calculations are exact; the interpretations are reported, in the conditional, and it is up to you to take from them whatever speaks to you.

It was born in Mesopotamia, where astronomers recorded the movements of the sky and drew omens from them for the king; the zodiac of twelve equal signs appears there around the 5th century BCE. In Hellenistic Egypt, it joined Greek geometry to produce the birth chart. Ptolemy synthesized it in the 2nd century in the Tetrabiblos, which was passed down by Arab scholars and then by medieval Europe. In the 20th century, authors such as André Barbault steered it toward psychology.

For your Sun sign, the date almost always suffices, except on the days when the Sun changes sign. The rising sign and the houses, however, require the time: the rising sign changes about every two hours, sometimes faster. The Moon, which moves about 13° a day, can also change sign during the day. Without a known time, our tools show a chart without a rising sign rather than inventing one, and flag the uncertain positions.

Your sign, also called your Sun sign, is the one the Sun was in at your birth: it depends mostly on the date. The rising sign is the sign that was climbing over the eastern horizon at the same moment; it varies with the time and the geographic position. The birth chart brings together everything else: the Moon, the eight planets, the houses, and the aspects between them. Tradition considers the trio of Sun, Moon, and rising sign the heart of a reading, far more telling than the sign alone.
